FRED W. PULLEN, OF GRAND RAPIDS, MIQHIGAN, ASSTGNOR 10 BISSELL CARPET SWEEPER COMPANY. OF GRAND .RAPIDS. MICHIGAN CAR-PET-SWEEPER CASE Application filed March 2 27 This inventionrelates to improvements in carpet sweeper cases.

The objects of the invention are:

First, to provide a simple and economical 5 construction especially adapted to a case with a sheet metal shell or similar sheet constructionl Second, to provide improved means of assembling such a structure so that the different parts can be finally finished before they are assembled.

Third, to minimize the number of nails or securing devices used.

Objects pertaining to details and economies of my invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure embodying the features of my invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a side elevation of my improved carpet sweeper case, the relation of certain parts being indicated by dotted lines.

Fig. 2 is an end elevation view from the right hand of Fig. 1, the position of certain parts being indicated by dotted lines.

Fig. 3 1s a longitudinal detail sectional view through the center of the case showing the method of assembly.

Fig. 4 is a detail side elevation of one of the side bars, the positionin of the ion itudinal groove and cross gains being in icated by dotted lines.

Fig. 5 is an enlarged detail perspective view of one end of one of the side bars.

Fig. 6 is a vertical detail sectional view of the preferred form of assembly, dotted lines indicating the method of manufacture and assembly.

-Fi 7 is a detail view of the end and top bar in disassembled relation showing the oint ap' earing in Fig. 6.

Yr ig. 8 is a detail sectional view similar to Fig.6 slightly modified, showing no case end depression for receiving the end of the top bar.

Fig. 9 is a detail view of a disassembled modified joint between the top bar and case e'Ifd with a rabbet groove to receive the end of the top bar.

Serial N0. 1 78.284.

3 f Thejparts fwill be referred toby then num'erals-of reference whic'li are the-same in all 'views.

i 1' is the sheet metal top andside walls of the case. 2,2 are the ends which each contains a central 'slot 21""forthe accominodati nof tfhe' brus'h spindle and'apertijires 22, 22 for the play of;theuisualf'spring airles'jfor'the floor wheels; 23 is the-hole fortheinturned-e'nd'of the 1 handle bail'. 124fis' a slight stamped de'-' presenter-tasted ofthet()p ba1 f. 3 3' are 5 side barge -which" are grooved' at 31 at, 'the 'gtop to receivefthe I lowejr'j edge of the sheet ca's'e wall 1 and; stiffen a'ndret'ain th same it pla'rce; l .iiThwends 615 I the sheet" metal case are turned messa es '11; s 'e"d tail in Fias. 6 and 8, Thecase ends are'in ted in place ndthelojve'r corner of each secured by nails 12 in the extreme lower edge. The side bars 3, which contain vertical gains 32 to receive the ends, are put in place and secured by nails 34.

The top bar 4 is then forced to place, depressions 24 having been stamped into the ends 2 to receive the same. The top bars are sprung to place and force the ends 2 securely against the beads 11, completely finishing the ends by that operation. While the top bar will remain in place, due to the tension, it is preferred to secure the same by a wire nail 41, see Figs. 6 and 8.

A rabbet 25 may be cut in the upper edge of the end 2 and the top bar 4 be swung into it as seen in Fig. 9.

It will thus be seen that the case structure is very staunch, the sheet metal is supported under tension, the beads formed on the ends of the same embracing the joint with the endcompletely encasing the same, making it possible to finish the exterior of the sheet metal case before assembly. As the nails are concealed, except those through the side bars, the structure can be assembled after it is finished very expeditiously. The side bars 3 extend at 33 to receive the usual guard bars. I

I would state that the structure as described is clearly capable of considerable modification without departing from my invention. Sheet metal is specified and is especielly adapted. Other sheet material is, however, available.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A carpet sweeper case, comprising a rectanguler; sheet metal shell -body' with clownturned sides and having inturned heads at the ends thereof, case ends conformed'to the said shell and having central depressions in their upper inner margins, and-rete1n1ng'- nails through the lower corners of the shell body into said ends, side bars grooveclat theirtop to receive the downturnededgesof the. sheet metal shell and gained to engage the said case endssanclsecured. to; said: case ends,
